ice_cfg_dflt_vsi(9)

💖 ice_cfg_dflt_vsi — a Kernel API Manual moment 💖

okay so bestie, welcome to the Kernel API Manual entry for ice_cfg_dflt_vsi(9) — yes the (9) means it's a kernel function, we're literally in the big leagues now 🫶

---

✨ NAME ✨

ice_cfg_dflt_vsi — flips the state of a VSI so it's either the default one or, like, absolutely not 💅

---

🌸 SYNOPSIS 🌸

int ice_cfg_dflt_vsi (struct ice_port_info *pi , u16 vsi_handle , bool
set , u8 direction );

---

🎀 ARGUMENTS 🎀

• pi — pointer to the port_info structure, the whole main-character port situation 🦋
• vsi_handle — the VSI handle you're crowning as default 👑
• set — true to add that switch rule we just talked about, false to remove it. yes it's a bool, yes it's that simple, slay
• direction — literally either ICE_FLTR_RX or ICE_FLTR_TX, pick your lane 🚦

---

🔥 DESCRIPTION 🔥

so what it actually does: it adds a filter rule that sets/un-sets the given VSI as the default VSI for the switch — and the switch is represented by swid, iykyk ✨
